BBC 34WS-6: Stoper for medium to hard rock

8311 0104 03

Atlas Copco Stopers are all-steel rock drills designed for production drilling, raise driving and roof bolting. They have a ratchet wheel rotationand and a short piston stroke for good penetration rates in soft and medium hard rock. Air blowing through the chuck when drilling, cleans the rotation chuck and lubricates the drill steel shank. The WR version has clockwise rotation and can be used for tightening or installing screen on threaded roof bolts. The BBC 34WS stoper offers extra power and torque for tough and difficult rock conditions. It provides air-flushing at the front head of the rock drill to prevent water and cuttings from entering the drill.
